It’s International Dark Sky Week, and we’re celebrating some of the public lands that are awesome stargazing destinations. Some of the last harbors of dark skies, public lands provide unspoiled views of the stars glittering above. Named the first International Dark Sky Park in 2007, Natural Bridges National Monument in Utah contains three beautiful natural bridges. At night, the bridges form a window into the sky, giving visitors a view of thousands of stars that are bright enough to cast a shadow. Visitors here can see up to 15,000 stars throughout the night.
